SWToR server issues lead to Patch 2.9.0d

"It’s no secret that since yesterday a number of SWToR servers have experienced a series of issues. Lag spikes, dropped connections and queues started with the Harbinger server, and then expanded to Begeren Colony and the Bastion. These issues eventually forced Bioware to take these servers offline for maintenance."
